Table 3. Comparison of chromosomal genetic tests
Method	Duration	Anomalies	Limitations
Array Comparative Genomic Hybridization (aCGH)	12 hours	Aneuploidies Translocations	False positives. It does not detect mosaics.
Single Nucleotide Polymorphism Array (SNP)	72 hours	Aneuploidies Translocations Parental Origin	Does not detect balanced translocations and mosaics.
Quantitative Polymerase Chain Reaction (qPCR)	4 hours	Aneuploidies	Does not detect segmental aneuploidies, translocations and mosaics.
Next-Gen Sequencing (NGS)	< 24 hours	Aneuploidies Mosaics Monogenic Diseases Translocations	Limited capacity to detect balanced translocations
